MINE-WORKING MACHINE Specification of Letters latent.

Appiioanon and January 24, 191e. semina. 731314.

' To all whom t may concern.' l

Be it known that I, N oR'roN A. Nnwnrox, a citizen of the United States,residing at Columbus, in vthe county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Mine-VVorking Machines,of which the following is a specification.

- This invention relates to mine working machines and is directedparticularly to loading machines for transferring the broken-down coalin coal mines 4into the mine cars.

' The main object of my invention resides in the provision of astructure whereby the coal layer is given arkerf cut by a swingingmovement of the machine as va whole and subsequently loading the brokendown coal by a similar -movement of the machine. In other words, the.novelty-of this invention resides in the combination of a kerf cuttingmachine and a conveyer structure so mounted and related to each otherthat they may be swung sidewis to cut the kerf whenthis kerf cutting`structure is in operative position, or to sweep the mine loo'r to gatherthe coal when the kerf-cutting structure is in inoperative position.This is broadly claimed in my Patent Number 1,278,196 September 10,1918. l

A further objectA of my invention resides in the provision of atwo-wheeled truck support; upon which the conveyor and peculiarlylocated kerf cutting structure are mounted, combined with mechanism forrotating one ofthe wheels in one direction and-moving the other wheel inthe other di'- rection, whereby the desired swinging movement may lbeobtained.

Other objects of my invention become.

more apparent after a further detailed description of the accompanyingsheets of drawings, wherein similar characters of reference designatecorresponding parts, and wherein:

:.[n these drawings, there is shown a base unit or truck, comprisingessentially a pair of traction wheels 1 loosely mounted upon an axle 2.Mechanism is provided whereby 'these wheels may be rotated in either 'aforward or rearward direction, or one of the wheels may be made torotate inone direction and the other wheel in the other direction, the4latter means being those at present employed for causing a side sweep ofthe machine as a whole. This base unit carries in superposed relation aconveyer designated generally by the reference numeral 3 and it will benoted that this conveyerv operates about driving and idler sprocketswhich are horizontally arranged. Further, this conveyer is provided withva, forwardly extending depressed extension 4 and al rearwardlyhorizontally arranged extension 5 vpositioned directly over anyl type ofconveyance. such as a mine car shown at 6. This entire conveyerstructure, as well 'as the-machine as a whole, is supported about ahorizontal pivot, -which in the present instance is the axle 2, thedepressed extension 4 serving as the means for supporting the forwardportion of the structure upon the mine floor.

Reference to Figs. 1, 5, 6 and 7 will show that the conveyer' structurecomprises a general framework formed of properly bent longitudinallylextending Z-bars 7 onto which there are secured the angle irons 9 toform an inclosure space 10 in which the chain 11 is confined. TheseZ-bars are thus rigidly mounted upon la pan structure I ing of the coalinto the .car 6 when -conveyed to this point by means of the? flights 14securely carried by the chain 11. In orderto 'always locate the dumpopening 13Voverthe mine car,` n'o matter in what position of swing theconveyer. structure may be, lI have provided this portion of theconveyer with a slide member 15 havin a supplemental opening 16 and thewhole s ide plate slidable back and forth beneath the opening 13 in thechannel members 17. By means ofl this structure, the point at which thecoal 1s discharged, may belocated according` to thel position of theopening 16. For purposes of convenience, the fli hts 14 are' providedwith cutter teeth 18 at t eir ends to cut their way into thev coal heapas the conveyer 1s operated. As will be noted from the drawing, theconveyer` trough orl pan 12 is flat practically throughout its entireworking surface and it is upon this that the coal rides in its ascentfrom the heap to the mine car, the angle irons 9 and the Z'bars 7forming the means of stifl'ening the trough. This trough is rigidlysupported on two sets of plates designated; -19 and 20, angle ironsshown at 21 forming the means of attachment in each case, as well asalsoproviding means for stiifening the trough as a whole. The lowerportions of these plates are securely fastened to bearing members 22,which latter are'piv otally or rotatably mounted about the axle 2, as isshown particularly in Fig. 5.

The manner of driving the conveyer is -as follows: Referringparticularly to Figs., 5

and 6, it will be noted that there is provided a motor 27 which issupported upon the axle 2 and upon a counter shaft 28. The arrhatureshaft 29 of this motor rigidly carries a gear wheel 30 which inturn'meshes with a gear wheel 31 loosely mounted upon the axle 2. Thisgear wheel 31 isprovided with va hub extensionl which forms a sprocketas shown at 32 and a chain 33, Fig. 7, passing over a sprocket 34 alsoengages this sprocket 32. The sprocket 34 is rigidly carried by a shaft35 supported in brackets 36 carried by the underside of the conveyerframe and this shaft isfurther provided with a second sprocket 37 overwhich a, chain 38 passes. This chain 38 also 'engages a sprocket 39fcarried on a shaft 40, which latter is also supported in brackets 41carried on the underside of the frame. Referring to Fi'g. 9, it will benoted that this shaft 40 is also provided with a worm 42 and this wormmeshes with a worm wheel 43 carried by one ofv the corner shafts of theconveyer. This' shaft has been designated 44 and its upperend isprovidedwith a drive sprocket 45, over which the conveyer chain 11 passes. Theremaining sprocket wheels 46 of the conveyerare all idlesprockets andare, therefore, loosely mounted on their respective shafts. Therefore,whenever it is desired to set the conveyer in operation, theswitch'governing the y opposite direction, the current to the motor may bereversed so that this motor itselfwill run in a reverse direction.

The mechanism (for controlling the bodily movement of the conveyer, willnow bede scribed. The axle 2,- as has been related, is

rovided with a air of traction wheels 1 oosely mounted t ereon andmechanism 1s rovided whereby these traction .wheels may oth be moved ineither a forward or reverse direction or one may be moved in a forwardand the other in a reverse direction, the latter arrangement beingprovided to cause the cony veyer to sweep the mine floor to gather allofthe dislodged coal. The counter shaft 28 is journaled in the sideplates a19 bymeans of hub boxes 47 and this shaftis further providedwith a gear wheel 48.which-is keyed thereto arranged to mesh with theymotor gear wheel 30. In this manner'the shaft 28 is rotated wheneverIthe motor 27 is setin operation and in order todrivel the tractionwheels, the shaft 28 has been provided with four friction clutchesdesignated respectively 49S, 50, 51 and 52. The cone portions, or theinside portions of each of these clutch members is rigidlyl connected.with'the shaft 28,

while the shell or outside member is loosely mounted on this shaft, buteach is provided with a bevel gear 53. `Meshing with these gears 53 arebevel pinions 54 mounted upon angularly disposed shafts 55, which lattercarry worms 56 on their lower ends. These worms then in turn mesh withworm wheels 57 loosely mounted on the axles 2 and housed within thehousings 58; The outside face of the hub of each of theworm wheels 57 isformed with a clutch designed to mesh with a clutch collar .2a looselymounted on the axle 2 and the opposite end of each clutch collar isvsimilarly formed with a clutch face to engage the hubs 59 of thetraction'l wheels 1. Each of the cone portions or movable portions ofthe friction clutches is provided with a groove 60 in which yoke 61operates. All of these yokes are slidably .mounted upon a rod 62securely fastened in the side frames 19 and the extreme upper ends ofthe yoke engaging clutches 51 and 52 are rigidly connected with a rod 63slidably mounted in the side plates 19, while the remaining two yokes orthose operating in conjunction with the clutches 49 and 50 are rigidlymounted in connection with slide rods 64. These two slide rods arecontrolled by means of handles 65 and 66 respectively, these handlesbeing mounted on each side of the machine as a whole, so that controlmay be effected when .the operator happens to be on either side of Thesehandles 65 and 66 are the machine. pivoted at their lower ends to theframe plates and are pivotally connected interthe friction clutches 49and' 51 and then through the medium Vof the gear wheelsv 53 and 54 onthe shafts 55 and the worm 56 and ythe worm wheel 57, the axle 2 will berotated in a forward direction. Movement of both of. the handles 65 and66 -in the opposite direction will bring the other two clutches intoworking operation to cause a reverse movement of the traction wheels.Movement of the handle 65 toward the left and lthe handle 66 toward theright will bring the working parts of the clutches 51 and 50 intoengagement and because both they traction wheels 2 and the worm wheels57 are loosely mounted on the axle 2,'the traction wheels themselveswill be rotated in opposite directions through the medium of the clutchcollars 2a. Therefore, this latter arrangement will cause the machine asa whole, to pivot about acenter substantially in the center ofthe axle 2and in consequence the forward end or the depressed extension 4 of heconveyer will be made to sweep the mine oor.

The kerf cutting structure used in connection with the present machinewill now be described: This kerf cutting structure is more or lessstandard at the present time, but the machine as a whole is mounted in asupplementary frame comprising the side frame plates '20, which latterare provided with a pair of oppositely dis osed rollers 67 and also at apoint farther orward with a pair of arms 68. These arms 68 are rigidlymounted on a shaft 69 which extends through both the frame plates 20 andalso the outside frame plates 19 and is provided with cranks 69a on itsoutside' ends. opposite ends of the arms 68 are provided with rollers68a and these rollers 68, together with the rollers 67 slide in channelmembers 69 which in reality form a third frame for the mining machineitself. As is well known, a minlng machine comprises what is known as astationary member and a movable or cutter member and it is upon thesechannel members 69 that the so-called stationary member is rigidlymounted to enable the kerf cutting machine as a whole, to be movedforward by sliding the channel members 69 over the rollers 67 and 68a.'

This stationary member comprises an angle iron structure 70 held proerly spaced by means 4of tie plates 71 and a front piece formed ofmembers 72 and 73. The an le iro'n framework is provided on its un ersurface with a pair of racks 74 by means of which the cutter member ismoved forward'. This cutter member comprises a pair of side channels 75of a well known construction ary member TheV- lwhich are securely heldspaced attheir for-l secured to the central bar 79 by means of a boltshown at 81 and further-'provided with laterally l extending ears 82which slide upon the upper surface of the angle station- 70. Upon thismotor support plate 80, the motor 83 is supported and the armature shaftof this motor carries a pinion 84. This latter pinion meshes with a spurgear 85 rlgidly mounted on a shaft 86 which 1s sultably Journaledin themotor support framework and which shaft is also provided wlth bevelpinions 87 and 88 and a worm 89. The p1n1on 87 meshes with a bevel gear90 mounted upon a shaft 91 which carries a worm 92 at its lower-end.This latter worm meshes wlth a worm wheel 93 loosely mounted on a shaft94 and it is this shaft on which the .control is mounted. The worm wheel93 itself isprovided with a clutch face 95 designed to coperate with aclutch collar 96 1tself slidably keyed on the shaft 94 and op. erated bymeans of a yoke lever 97. -On each end. of the shaft 94 there is mounteda spur pimon 98 which coperates with one of the racks 74 and, therefore,when the clutch collar 96 is shifted to a osition of engagement with theworm 95, this shaft 94 is caused to rotate, which in turn causes thepinions -98 t0. engage the rack bar 74 to cause a forward feed. Toretract the slide or cutter member, the worm 89 is provided. This worm.89 meshes with a worm wheel 99. This worm wheel is mounted on a shaft100 which carries a worm 101 at its other end, which worm is designed tomesh with a worm wheel 102 also slidably mounted on the shaft. 94 andthis' worm wheel is further provided with a clutch face 103. Thus, whenthe clutch collar is moved to engage the clutch face 103, it is out ofengagement with the'clutch face 95 and, therefore. the worm wheel 93 isidle on this shaft, while the worm wheel 102 is rigidly connected withthe same. Because of the driving connection between the shaft 86 andthis worm wheel through the medium of the worm 89, worm wheel 99 andworm 101, the shaft 94 will be rotated in a direction reverse to thatpreviously described, thus causing a rotation in the reverse directionof the spur pinions 98, which in turn causes a retraction of themachine. To drive with the bevel pinion 88 which meshes with a bevelgear 104 which latter is in tn rn mounted ona shaft 105 which carriesa'drlvin sprocket 106 for these cutter chains. 4

n -order to positively force the kerf cutting machine 1n either aforward or rearward direction, I have provided both channel members 69with a rack 107, p'mions designated 108 beino' designed to mesh withthese racks. mesh with driving ears 109 mounted on a cross shaft 110,whlch shaft is provided at its outer end with a crank 111. This shaft isfurther provided with atoothed wheel '112, with which the pivoted dog113 coacts to hold the shaft in lany desired position, the shaft itselfbeing held against turning so long asthe dog 1s in engagement wlth anyone of the notches shown in the wheel 112.' Thus, by turning the crank111, the entire kerf cutting machine may be moved f orwardly by means ofthe gear connection with the rack 107 on the underside ofthe channelmembers 69.. After the kerf cutting structure has been extended to thedesired distance, it may be locked 1n thls posltion by dropping the dog113 into the de-l sired notch 1n the wheel 112. After this, the

*movable portion of the kerf cutting machine may be extended as .iscustomary. By reversing the direction of movement of the crank 111, theentire kerf cutting machine may also be retracted to its retractedposition, as is shown in Fig. 1.

In order to provide a structure whereby a kerf cut may be made at anydesired angle to the horizontal, I have provided the arms 68already'referred` to, these arms carrying rollers 61 at their outerends. of these arms are rigidly connected with the shaft 69 Aand uponthis shaft there is vrigidly mounted a notched wheel 114 with whichthe..

dog 115 coacts. By turning the crank 69, the arms 68 are moved and theentire kerf cutting machine then indsits pivot'about the rollers 67. Inthis manner the entire kerf cutting machine may be elevated or .loweredto any desired inclination and the structure held in this position bydropping the dog 115 into thecorresponding notch on the notched wheel114.

neath the pivoted rollers 67, this tilting movement may beheifectedwithout wedging or breaking any of the parts, inasmuch as only a verysmall amount of play is necessary to accommodate the movement of the`kerf cutting These pinions in vturnv The rear ends' y Because of thelovcatlon of the driving pinion 108 directly' becut the-kerf, the kerfcutting structure is moved forward by a turnin of the crank 111.`Anydesired position` o inclination of this kerf cutting structure mayalso be obtained by an operation of the crank 69E. Because of itslocation, this kerf cutting strucy'ture will make what '1s commonlycalled a center cut and if it is properly positioned, the cutter chainmay be started in operation and fed forwardly as is customary. Afterthis cutterchain .has been fed into the coal face the desired distancethe entire machine as a whole, may be swung about a vertical pivot byrotating one of the traction wheels 1n one directlon and the othertraction wheel in the other direction. After this kerf cut has beencompleted, the kerf cutting machine is retracted to its inoperativeposltion and, after the coal has been broken down in any desired manner,the same movement as'outlined for the kerf cutting machine, will sweep'the depressed extension of the conveyer structure across the mine floorto gather this broken down coal. It will thus be apparentthatconsiderable time is saved, 1n that it is not necessary to move fromplace toplace during the continuous operation of mlnlng and further itis not necessary to emloy two distinct machines for accomplish-` thecoal from above the front end of said conveyer and relatively movablewith respect to said conveyer-structure to assume an operative orinoperative position, the means for driving said two structuresindependently of each other and means for swinging said conveyer andkerf cutting structures sidewise to cut the kerf when said kerf. cuttingstructure is in operativeposition or to sweep the.
